Breakthrough Science for Severe Viral Lung Infections

We are a specialist respiratory biotech company whose primary focus is developing our investigative inhaled IFN-β (SNG001) for the treatment of severe viral lung infections, including COVID-19, as potentially the first host-directed, broad-spectrum antiviral treatment delivered directly into the lungs.


Host-directed antivirals boost the cell’s immune responses, strengthening antiviral defences, so they are better able to fight off the virus.

Not all antivirals are the same

Watch this short animation to learn the difference between host-directed antivirals and direct acting antivirals.

The Need

There remains an urgent clinical need for new therapies to treat those hospitalised with severe viral lung infections, including COVID-19, to prevent the progression to more severe disease and death.

Viruses are wily creatures, and you’ve got to stay ahead of them. I think it would be naïve to think that if you get one or two good drugs, you don’t need any more — not when you have a virus that has already killed 760,000 Americans.
